Application-filed July 19, 1807; Serial 10. 384,627.

To all whom it may concem:

Be it known'that I, G-noncn W. FERGUSON, acitizen of the United States, a resident of the city of Springfield, Greene county, and State of Missouri, have invented certain new and useful Improvements in Automatic Photographic-Printing Machines for Print ing Photographs from Ne atives by the Use of Sunlight; and I do hereby declare the following to be a full, clear, and exact description of improvement.

The object of my invention is toprcvide convenient means for rapidly printing photographs from negatives by giving each photograph of the number required the same means of an automatic arrangement, which makes each photograph exactly the same. By this method photographs may be printed when ever desired without the aid of sunlight as in the old method.

,VVith these objects and others of minor importance and with this general mode of construction in view and particularly pointed out in the claims, the following specification will develop in detail the mam nor of construction, and'will point out how these objects are fully accomplished, when" taken in connection. with the accompanying drawings forming part of the specification in which Figure 1, shows 3. perspective view of the machine complete. Fig. 2 shows a plan View of the lever. Fig. 3 shows view of the regulating rod.

As shown in the drawing, A represents the rectangular box of convenient size with a lid, B. A represents opening in box A through which lever X operates. ()n lid B is secured a. pad of felt D represents the negative. .1

E represents the plateof glass securely fitted in the top of box A.

F represents the reflector of polished metal, which is securely fastened to box A.

G is the red incandescent light held in the socket H. Socket H, is fastened to the neflectorbottom.

H is an electric wire connecting red light G and the wcket N.

,H is an electric wire connecting the red light G and the her M.

N is a socket to receive an electric light extension. 'ihe lid B operates on hinges O. L is the bend which holds the rod K in place. The lever K is fastened to the side of box A by means of the stud Kfionvwhich it rocks, and to the rod K by the pin P.

N is the wire which connects the stud K with the socket N. When the lid B closes down on the box A, lid B comes in contact .with the rod K at K and presses it down.

In so doing the lever K breaks the contact at the point M and the red light G goes out.

It is the spring screwed to the bottom of box A, and to the lever K to bring same in contact with bar M, causing the red light G to burn when the lid B is raised. A curved plate of metal S is fastened to box A to cover the opening S which serves as a ventilator and a sight hole.

T is an air cylinder with a plunger T fitted inside. i

l T is a. rod fastened to the plunger T and the plate of copper U. A strip of copper \V is secured to box A by means of smal screws W. The lever X is secured to box A by pivot screw X. and is connected with the plunger rod T at one end, and to the link X at the other end, by the pin P A metal plate Y has oneend cut out to receive the link X and is secured to lid B by screws Y Link X and strip Y are held together by the pin Y Z is the regulating rod fitted at the to with a timing arrangement. Z timed an divided into seconds up to one minute, to regulate the time of exposure.

T is a small opening in the air cylinder.

By moving the regulating rod Z to the right or left the valve end of the regulating with the stud K. The electric wire H connects the socket H with the copper strip W at The electfid wire'H" connects socket H with the air cylinder H i v v, fie onerate, lhe coir i is placed on 1- with the eznzensi Wire from chandeiier or cennectei with the sec vt N.
